Left: Section of the original VIS image (900 pixels × 900 pixels, 90″ on the side) displaying standard features, specifically extended cluster galaxies, stars, background galaxies, and optical ghosts near bright stars, which appear as faint round structures. Middle: Ring-filtered version enhancing extended sources and removing compact ones. The red circles (10″ in diameter) mark the dwarfs from our catalogue of members. Right: SourceExtractor segmentation map confirming detection of all dwarfs and maintaining a low count of other detected sources.
